AI inference startup Baseten is reportedly close to finalising a $1.5 billion funding round at a $13 billion valuation, according to the WSJ. This figure marks a dramatic increase from its $300 million Series E raised just five months ago, which valued the company at $5 billion. The latest deal is described as a split-priced round, where some investors are entering at $13 billion while others participate at $11 billion. This structure allows lead investors such as Spark Capital, Sands Capital, Altimeter Capital, and Wellington Management to secure headline valuations that appear more impressive on paper. Co-led by these firms, the round comes just nine months after the company secured a $150 million Series D, highlighting a period of intense financial activity for the London-based firm since its 2019 launch.
This surge matters because it underscores the continued investor appetite for the inference layer, a critical component of the AI stack that handles requests after a user submits a prompt. While the valuation jump reflects the broader “inference gold rush” described by The Next Wave, the split pricing tactic suggests underlying market caution. By routing requests to competent, less-expensive open source alternatives, Baseten aims to control costs and improve speed, yet the inflated headline numbers may mask the reality of a slowing AI market. The discrepancy between the actual capital raised and the reported valuation indicates that investors are prioritising narrative strength alongside genuine growth potential in this sector.
- Baseten is targeting a $13 billion valuation, representing a 160% increase in less than six months.
- The round employs split pricing, with some investors entering at $11 billion to adjust headline figures.
- Co-led by Spark Capital, Sands Capital, Altimeter Capital, and Wellington Management, the deal focuses on cost-efficient inference routing.
